    摘要: A semiconductor device having a capacitor and a method of fabricating the same may be provided. A method of fabricating a semiconductor device may include forming an etch stop layer and a mold layer sequentially on a substrate, patterning the mold layer to form a mold electrode hole exposing a portion of the etch stop layer, etching selectively the exposed etch stop layer by an isotropic dry etching process to form a contact electrode hole through the etch stop layer to expose a portion of the substrate, forming a conductive layer on the substrate and removing the conductive layer on the mold layer on the mold layer to form a cylindrical bottom electrode in the mold and contact electrode holes. The isotropic dry etching process may utilize a process gas including main etching gas and selectivity adjusting gas. The selectivity adjusting gas may increase an etch rate of the etch stop layer by more than an etch rate of the mold layer by the isotropic wet etching process.

    摘要: In a method of manufacturing a semiconductor device such as a SONOS type semiconductor device, a trench is formed on a substrate. An isolation layer protruding from the substrate is formed to fill the trench. After a first layer is formed on the substrate, a preliminary second layer pattern is formed on the first layer. The preliminary second layer pattern has an upper face substantially lower than or substantially equal to an upper face of the isolation layer. A third layer is formed on the preliminary second layer and the isolation layer. A fourth layer is formed on the third layer. The fourth layer, the third layer, the preliminary second layer pattern and the first layer are partially etched to form a gate structure on the substrate. Source/drain regions are formed at portions of the substrate adjacent to the gate structure.
